MAN U FACTU RE OF BOTTLES.

SPECIFICATION forming part of Letters Patent No. 512,137, dated January 2, 1894.

Application filed March 20. 1893. Serial No. 466,818. (No model.)

a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in the Manufacture of Bottles; and I do hereby declare the following to be a full, clear, and ex act descriptionof the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to the manufacture of glass bottles and has especial reference to means for forming the head of the bottle shown in the patent granted to me January 31, 1893, No. 490,729.

The invention will be fully disclosed in the following specification and claims.

In the accompanying drawings which form part of this specification, Figure 1. represents a side elevation, partly in section; Fig. 2. a top plan view 5 Fig. 3. a transverse section on the line so a: Fig. 2; Fig. 4. a vertical longitudinal section of the mold detached and on an enlarged scale; Fig. 5. a transverse section of the mold, and Fig. 6. a side view of a bottle head, the product of the invention.

Reference being had to the drawings and the letters thereon Aindicates a table or stand; 13 a two part mold provided with hinges a a, a hasp b and a cavity 0 which conforms to the upper part of the neck and head of an ordinary bottle used for transporting liquids. At the outer end of the cavity 0 is a seat d which forms a support for a rod 0 which is further supported in brackets e e on the table; and in the upper part of the mold is avertical passage f through which the molten glass is supplied to the mold. In'the lower part of the mold is a vertical transverse slot g to receive a flat rectangular bar D to form the transverse slot or seat h in the head E of the bottle, as shown in Fig. 6.

F indicates a bracket provided with arms 7; i which guide the plunger G in its reciprocations, and said plunger is reciprocated by a lever H supported on an arm is of .the bracket F and engaging two pins or studs Z l alternately; the plunger being provided to press the glass into the mold through the passage f when required.

The rod 0 may be provided near its outer end with a slot m through which the outer end n of the lever I passes to push the rod into the mold and withdraw it therefrom,and the bar D may be connected at its lower end to a foot lever K by means of a rod 0 for the purpose of raising the bar and projecting it into the cavity 0 of the mold and withdrawing it from the cavity of the mold. The bar D is provided with a pin or shoulderp to limit its extension into the mold, andv with a cylindrical aperture or eye q thrdugh which the rod 0 passes to hold the bar in its proper position in the mold.

L indicates the bottle, supported in a cradle M movable longitudinally on its guide 4 on the table A to insert the neck of the bottle into the inner end of the cavity a of the mold and to support the bottle while the head E is being formed thereon.

In the manufacture of bottles in accordance with my invention the bottle is blown in the usual manner with or without an ordinary head on it. If blown with a head, the head is severed from the bottle as soon as it is removed from the mold and the neck of the bottle inserted in the furnace and reheated, when the bottle is placed in the cradle M and the neck of the bottle inserted in the cavity 0 of the mold. Molten glass is then poured into the mold B through the passage f, and the bottle revolved to form a union between the end of the neck of the bottle and the molten glass; when the bar D is raised into the mold and the rod 0 pushed into the outer end oft-he mold and through the eye q in the bar D, thus forming the transverse slot or seat h in the head of the bottle. The union between the neck and the head of the bottle may however be made by pressure, in which practice the bar D and the rodC are projected into the mold, the bottle placed in the cradle and the neck of the bottle inserted in the cavity of the mold and the cradle locked in position by any suitable means; when the molten glass is poured into the mold and the plunger pressed down upon the glass in the mold with sufficient force to form a union between the two bodies of glass.

Having thus fully described my invention,

what I claim is- 1. The improvement in the art of making bottles, which consists in forming the. body and the neck of the bottle and subsequently providing the bottle with a head having a, grittilsverse slot'crossing the mouth of the 2. In apparatus for making bottles, the combination of a mold, a vertical bar and ahorizontal rod constructed to enter the mold and form .a transverse slot in and across the head- 20 5. The combination of a mold, a bar having an eye in one end, a rod adapted to pass through said. eyeand within the. mold; and means for reciprocating said bar and rod.

6. The combination of a mold for the head of a bottle, means for forming a transverse slot in and across the head and means for forming the mouth of the bottle; and a movable cradle for supporting the bottle.

7. The combination of a mold, means for forming a transverse slot in and across the head of a bottle, and means for forming the mouth of the bottle, a movable cradle to support the bottle, and a plunger to force the glass into the mold.

I In testimony whereof I affix my signature in presence of two witnesses.
